I have a contour data file downloaded from UK Ordnance Survey, which gives 2d contours of an area in gml format (also supplied in .shp format) with the heights of each contour attached to the attributes of each line.
I want to give the contours a Z value of the height attribute attached to it, so that I have a 3d contour file I can then use in QGIS to create hillside shading etc, and potentially export to dxf/dwg.
Is there a way to do this without manually moving each line?
I was hoping for an actual tool I can use, as I have no script experience.
